Hard drives can be affected by corruption, data block failure, and even physical damage. While there are a number of Mac hard drive repair software solutions that can help with these issues, choosing between them isn’t easy.

We tested dozens of these products and narrowed down our top choices down to the 7 best Mac repair tools. This article breaks down everything a user needs to know to choose the best Mac disk utilities for their needs.

The 7 Best Repair Tools for Mac in 2026 (Paid and Free)

To properly evaluate each Mac disk repair software, we broke down their main features, pros and cons, compatibility, and price. By the end of this article, you should have a clearer idea of what these tools can do for you, and which utilities to download depending on your situation.

1. Disk Drill

Disk Drill is primarily a data recovery tool with several important and free features that are crucial when repairing a defective drive. Data loss is a very common occurrence during disk repair, and Disk Drill is capable of restoring files from corrupted drives–so you can secure your data before trying to fix it. You can also run Disk Drill from Recovery Mode, which is a safer method that avoids further impact on the drive from your Mac’s operating system.

One of its free features is called Byte-to-byte backup, which is a powerful image backup tool that was recently reworked in version 6 to work more carefully with disks in poor condition (allowing you to back up as much disk space as possible). You can use this backup file as the data recovery target later, instead of scanning your drive directly.

Another free feature is Disk Drill’s S.M.A.R.T. monitoring module, which allows you to monitor your drive’s health status using different hardware indicators on the disk. The app has several other powerful features, but since they aren’t as relevant to disk repair, you can read about them in our dedicated Disk Drill review.

Overall, while Disk Drill isn’t a traditional disk repair tool, it’s an important step of the process if you care about preserving your data. It’s also powerful, affordable (as far as data recovery software goes), very beginner-friendly, and has many free features (including the ability to preview scanned files for free, which is excellent for recon purposes). But if you just want to fix your drive and don’t care about your data, you won’t really need this app.

Main Features

• Advanced Recovery: Even if your hard drive doesn’t appear in Finder, Disk Drill will still be able to read it. However, note that your drive does have to appear in Disk Utility with the correct storage size.
• S.M.A.R.T. Monitoring: S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) is a feature built into most modern drives to detect any issues that may lead to potential failure, which can often point you to the right direction and pre-empt damage escalation. Disk Drill lets you view this information in-app and via an icon on your Mac’s menu bar.
• Byte-to-byte Backup: Creates disk and partition backups for your data in a byte-to-byte disk image (DMG), in case recovery is needed. An additional precaution you can take is to first create an image backup of your drive and attempt recovering data from that image using Disk Drill. This lets you interact with the damaged drive as little as possible.
• Recovery Vault: Recovery Vault is another free feature that makes copies of your files’ metadata in the background. This makes it vastly easier to restore files in case data loss occurs in the future.
• Guaranteed Recovery: Similar to Recovery Vault, Guaranteed Recovery is a free protective feature that makes full copies of any files that you delete, so data loss is never truly permanent.

Pricing

• Free Basic version (free data recovery only from Guaranteed Recovery backups)
• $89 annual subscription (available on the CleverFiles website)
• $149 lifetime license (one-time payment)

System Requirements

• Intel 64
• Apple Silicon
• Older versions support Mac OS X 10.5+, while the current version supports 10.15.7+

2. Disk Utility

Disk Utility for Mac is Apple’s own built-in disk tool located in the Applications > Utilities folder.  It’s a spartan but powerful utility with everything most users need to manage their disks and protect their data. Most importantly, its First Aid feature can scan your volumes for formatting and directory errors and attempt to repair them automatically. If you’re experiencing slowdowns, interface glitches, software that won’t run properly, etc., Disk Utility may help.

Disk Utility is free and is the first tool you should try after restoring and backing up your data. Unlike Disk Drill, Disk Utility may directly repair the affected drive, and the process may cause data to get overwritten on the disk.

Main Features

• First Aid: A Mac disk repair tool that reports and automatically fixes any errors that it finds on your drive.
• Restore: Create a full backup of your drive volumes before attempting recovery, repair, or reformat to avoid further data loss. This is a decent alternative to Disk Drill’s Byte-to-Byte Backup, but Disk Utility doesn’t have the ability to restore data without any backups. You’ll still need a data recovery tool if your drive has already been corrupted and/or suffered data loss.
• Erase: Format your drive for a fresh installation or to address infections or corruption – note that formatting erases all your data so perform a backup first.
• Partition: This is more of a preemptive feature – divide your disks into partitions so any damage to the disk is usually contained.

Pricing

• Free (Built-in to macOS)

3. Drive Genius

Drive Genius is a feature-rich drive management and disk repair suite. The good thing about Drive Genius is that you can conduct maintenance on your drive with different approaches. Features range from rebuilding data, to scanning for malware, to correcting damaged areas on your drive. If you can’t isolate whatever has damaged your drive, Drive Genius is a great way to resolve multiple problems with one app (it’s also a good choice if you want to try multiple fixes right at the beginning).

Main Features

• DrivePulse: Get alerted of hard drive issues and potential major problems, and run a S.M.A.R.T. check to preempt further damage and/or data loss.
• Malware Scan: Looks for malware in files and data, which may be causing the drive corruption.
• Consistency Check: Detect and repair errors and possible file and folder corruption on your hard drive.
• Physical Check: Revive damaged areas on your drive, and run an Extended Check to read and write the data on your drive, which allows Drive Genius to find hidden problems on your drive.
• Rebuild: Data becomes unreadable when they lose their file name – Drive Genius’ Rebuild feature lists lost file names to the file data, allowing you to access your data again.

Pricing

• $79 (standard license, annual payment)
• $99 (standard license, one-time payment)
• $299 (professional license, annual payment)

System Requirements

• Supports macOS 10.12 (Sierra) and later
• Internet Connection

4. OnyX

OnyX is a completely free disk maintenance, optimization, and cleanup tool for Mac power users. It provides system-level configuration features, as well as direct access to operating system maintenance scripts that are typically blocked from the user (or only accessed through Terminal commands).

Examples of these features include tools to spot inconsistencies in your disk’s file system, rebuild important system databases, purge system-level caches that end up causing performance issues, and a lot more.

OnyX is extremely powerful and has finer control and deeper access to macOS–so much so that we only recommend this app for users who are already familiar with how it works or are willing to read the documentation and learn how to use it safely. If the learning curve doesn’t intimidate you, the app is definitely worth trying for fixing your Mac drive and keeping your system as clean as possible without resetting it.

Main Features

• Verify: Verify the structure of your file system and check for inconsistencies (a good alternative to Disk Utility’s First Aid feature if you want to jump into OnyX straight away).
• Rebuilt: Rebuild and reorganize your databases, and make it easier for your Mac to access the data it needs while operating. This may help with problems related to apps whose files may have gotten lost or deleted, causing issues while attempting to run them or while they’re running in the background. It can also speed up boot times and increase responsiveness.
• Clean: Clean up all unnecessary and redundant files from your system, apps, logs, and more. This function may help with slowdowns, and may delete unwanted files that are causing harm to your system.
• Process: Record logs of commands being executed and system resources being used, which may point to what caused the problem on your drive.
• Checksum Verify the integrity of your files, and detect errors caused by changes in the file data. Potentially identify what’s causing issues on your Mac.
• Maintenance Scripts: OnyX can run prebuilt scripts that periodically optimize your Mac, such as clearing up system caches, rebuilding databases, deleting unwanted application files, and more.

Pricing

• Free

System Requirements

• Supports Macs with Apple Silicon or Intel-based chips using macOS Tahoe or later
• The app has older versions that support older macOS systems, starting with Mac OS X 10.2

5. DriveDx

DriveDx cannot repair a malfunctioning drive. But it can tell you well before anything happens that something is wrong, what you need to do, and how quickly you must act to minimize the damage and protect your data. It can summarize your drive’s status at a glance but also provides dozens of indicators that can help you isolate the issue and determine the best course of action. “Prevention is better than cure” definitely applies to storage devices – so DriveDx is a solid investment.

Main Features

• Comprehensive Monitoring: Tracks a vast number of impending drive failure indicators, giving users the best chance of protecting their data and prolonging their drives’ lifespan.
• Self-tests: DriveDx conducts routine electrical, mechanical, and performance-based tests on the drive as it runs in the background.
• Automated reports: Get notified of any problems or changes to your drives’ status via email. You can configure the specific criteria that determine when reports are created.

Pricing

• $19.99 for the personal license (one-time payment)

System Requirements

• macOS 10.9 and above

6. TestDisk

TestDisk is a free Mac disk utility that was built for recovering important files from corrupted partitions and fixing corrupted hard drives. TestDisk, and its sister software PhotoRec, are popular open-source apps with powerful features – but their user interface can be intimidating as they look and function like Command Prompt. If you know your way around system commands, TestDisk and PhotoRec is a good combo to first restore data (then back it up with Time Machine) and then attempt file system recovery.

Main Features

• Partition recovery:  Recover deleted partitions, rebuilds partition tables, and rewrite the Master boot record (MBR).
• File system repair: Repair specific logical file system corruptions; TestDisk supports  FAT12, FAT16, FAT32, exFAT, NTFS, HFS+, and extended file systems.
• File recovery: Downloading TestDisk automatically downloads PhotoRec as well, which is a free data recovery tool that can restore lost files (it doesn’t have a GUI either, though).
• Boot sector repair: Repair corrupted or damaged boot sectors using existing backups or regenerating new ones based on file system specifications.
• Write found partitions: TestDisk can also rebuild or repair missing partitions using the partition data it found during the scanning phase, which makes the disk accessible again.

Pricing

• Free

System Requirements

• Mac OS X 10.6 and newer

7.Techtool Pro 21

Techtool Pro 21 is a powerful, extensive, and well-respected diagnostic and repair kit. It’s capable of repairing structural damage on your disk’s file system, and it has several advanced tools that can bypass macOS security features that block other apps or prevent deep repair operations. It’s also compatible with disks running most common formats, including HFS+, APFS, FAT32, and ExFAT.

One of Techtool Pro’s biggest strengths is that it has unique tools that can fix drives holistically, rather than only targeting known and obvious damage. For example, it has an advanced memory testing feature that checks the integrity of your RAM chip; while this isn’t a disk-specific repair feature, disk errors often occur due to faulty RAM (e.g., data corruption). No matter how well you can repair your disk, your faulty RAM will still cause disk errors.

It also has several quality-of-life features, like the ability to create an emergency startup disk and a portable toolkit using Techtool utilities (and your own), making it capable of resolving many different forms of corruption and logical damage.

Overall, Techtool Pro 21 is packed with repair and maintenance features, making it a must-have for power users. However, it’s definitely a large investment; if you don’t need a dedicated disk management powertool that you plan to use multiple times, you might be better off spending less on simpler tools.

Main Features

• Disk repair: Perform extensive repair on severely defective disks using Volume Rebuild, which is a process that Techtool Pro uses to reconstruct all of your drive’s data into a fresh and optimized directory.
• Techtool Monitor: Techtool Monitor is an optional download that you can install and run in the background to monitor your disks’ health status in real time. You can also configure it to save APFS Snapshots, which allow you to restore any files lost due to drive errors.
• Memory testing: Test your Mac’s RAM for hardware integrity issues; problems with RAM can often manifest as disk errors and disk-related malfunctons, resulting in false leads.
• File testing: Verify your files and check for corruption. You’re notified if Techtool Pro finds corrupted data, helping you reclaim space from unusable files and prevents that corruption from affecting macOS as a whole (e.g., opening a corrupted file can crash your computer).
• Test tracking and suggestions: Track your disk testing sessions and their results, and get suggestions from the app for the next scheduled maintenance run.
• Emergency startup disk: Utilize eDrive to boot into systems with a missing or damaged startup disk. You get access to Techtool Pro’s repair kit, certain Apple utilities, as well as other programs you can add yourself.
• Techtool Protogo: Create a bootable and portable diagnostic USB drive using Protogo, which allows you to take Techtool Pro’s kit anywhere with you, along with any utilities you want to install yourself.
• Volume cloning: Back up your files (and your entire drive) using the Volume Cloning feature, which creates an exact duplicate of your disk.
• Advanced hardware testing: Track the health status of the hardware components on your Mac, including your battery, fan, and sensors.

Pricing

• $89.60 (annual payment; $100.80 for subsequent years)
• $123.20 (one-time payment; updates stop after one year from the date of purchase until you subscribe or purchase another license)

System Requirements

• macOS 13.5 (Ventura) and newer

Honorable Mentions

In this bonus section, we’ll briefly cover three additional disk repair tools for Mac that fell short of our top 7 but have shown enough promise during our testing to still be the best alternatives. Each tool we featured below also has its own unique approaches to repair – and one of them already comes with macOS!

• DiskWarrior. A well-known repair tool that specializes in rebuilding directories — it can not only help restore access to files that were inaccessible due to corruption but it can also repair errors preventing macOS from booting properly.
• Fsck (File System Consistency Check). Native macOS tool that you can run in the command line (requires Single User Mode). It can fix startup issues, unresponsive drives, and persistent disk errors.

How We Selected Hard Drive Repair Tools for the List

However, beyond pricing, features, and other product-based factors, the most important consideration is if the tool is suitable for your own situation. No-brainers include data recovery and backup tools, because you don’t want to interact with a damaged drive without securing your data first.

When it comes to repair, in some cases Disk Utility will be enough. In other cases, you’ll need to use multiple tools to address a severely damaged drive. This article should give you a rough idea of the different ways hard drive failure manifests, and what tools have the ability to address them. Just make sure to always recover and backup your data first!

Here’s a Tip to Maximize Disk Repair Software

Many disk repair apps on this list are very powerful and can often work on their own; but oftentimes, severe disk issues are better resolved–and even prevented–by using multiple tools in synergy.

For example, use Disk Drill to create an image backup of your drive as well as recover your data (to prevent accidental data loss during repair or when your drive breaks down). Then, use Disk Utility for basic checks and fixes.

Finally, you can use an app like TestDisk to repair your drive’s partitions or Techtool Pro 21 to rebuild your volume directory–these are heavy-duty operations that should always come last in the workflow, especially if you can’t afford to lose data.
